TPAP2112K-3.3TRG1
TECH PUBLIC
Needs validationmedium risk
Strong functional alternative with matched voltage, higher current, but requires PCB redesign for SOT23-5 package.
Best Alternatives to TPTLV70033DCKR
TPTLV70033DCKR is a 3.3V, 300mA LDO in a compact SOT353 package. While no direct drop-in replacement is available, several functional alternatives exist in the SOT23-5 package that may work with a PCB redesign.
AI replacement insight
Package riskhigh
Requires PCB redesign. SOT23-5 is larger than SOT353.
Electrical risklow
For top candidates, electrical specs are comparable or better, but some have a higher min Vin.
Sourcing risklow
Candidates are from common manufacturers and appear to be actively sourced.
Can it be replaced directly?
Direct replacement for TPTLV70033DCKR should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
TPAP2112K-3.3TRG1 is the best electrical match, offering higher current and lower quiescent current. However, it requires a PCB redesign for its SOT23-5 package.
Main risk
The primary risk is the package mismatch (SOT353 vs. SOT23-5), which necessitates a mandatory PCB layout modification.
